Yeah 193cm is not an issue. He's taller than Darling, Lloyd, Lucas and Fev, the same height as N Riewoldt, Neitz, Roughead and Schulz, and two cm shorter than Franklin, J Riewoldt and Gehrig (and Hogan). Doubt anyone would call those blokes undersized.
It seems Lockett and Carey wouldn't make it as key forwards today.
But I have a more pressing question – who are these Goliath full-backs that render 193cm forwards redundant ?
